2.4 Special hazards

WARNING!
For hazardous media such as oxygen,
acetylene, flammable or toxic gases or
GB
liquids, and refrigeration plants, compres-
sors, etc., in addition to all standard regula-
tions, the appropriate existing codes or
regulations must also be followed.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct
danger of death.
The instrument may only be installed and
■
mounted by skilled personnel.
Before replacing the fuse, the calibrator
■
or the micro calibration bath must be
disconnected by unplugging the mains
cable from the power supply outlet.
WARNING!
Residual media in the dismounted instru-
ment can result in a risk to persons, the
environment and the equipment.
Take sufficient precautionary measures.
Thermal fuse
WARNING!
For safety, the calibrator or the micro
■
calibration bath is fitted with an
independently-operating temperature
fuse, which cuts out the heater power
supply if the temperature inside the
enclosure is too high. Once the metal
block and the liquid bath have cooled
down, send in the calibrator or the micro
calibration bath to WIKA for examination.
The calibrator and the micro calibration
■
bath have been designed as measuring
and control instruments. With any opera-
tion of the calibrator/micro calibration
bath not expressly provided for in these
operating instructions, additional protec-
tive measures must be taken.
The calibrator or the micro calibration
■
bath must NOT be used in explosive
atmospheres (flammable or explosive
atmospheres) without adequate protec-
tion.

2.5 Safety instructions for using calibration liquids

Calibration liquid, water
Only use distilled water, otherwise the
calibrator tank can become strongly scaled
and soiled.
Calibration liquid, silicone oil
WARNING!

Wear safety goggles!
Do not allow silicone oil to come into contact
with the eyes.
WIKA operating instructions, models CTD9100, CTB9100, CTM9100
Since a malfunction of the calibra-
tor/micro calibration bath can cause
personal injury or damage to property,
the equipment must be protected
by additional electro-mechanical
safeguards.
Only use the silicone oil recommended
here.
Before working with silicone oil, read
the material data safety sheet. This can
be requested from the manufacturer or
supplier.
When working with silicone oil, sufficient
ventilation should be ensured in the
room since it can give off pollutants.
Since silicone oil is hygroscopic, after
use, always close the calibration bath
using the transport cover.
The transport cover is fitted with a
safety valve. If the micro calibration bath
is closed when it is still warm, exces-
sive pressure can build up. In order
to avoid overpressuring, which could
lead to damage to the liquid bath, the
safety valve is activated at a pressure
of approx. 2.5 bar. This can lead to hot
vapour escaping.
